If y>0, find the range of all possible values of y such that \(\lceil{y}\rceil\cdot\lfloor{y}\rfloor=42\). Express your answer using interval notation.

Notice that if y > 0

6 < y < 7...... will make this true

For example....if y = 6.1

The ceiling = 7

And the floor = 6

What about the negative options? Oh yah.... y>0 Haha
